Smokey and the Bandit (1977)
Just when you thought CB radio was dead, the Federal Communication Commission passed a rule that might have every "Smokey and the Bandit" fan yearning for another sequel. The FCC is allowing FM transmission on CB radio!

In 1940, before the world would be plunged into a half decade of devastating conflict, a larger-than-life cartoon creator teamed up with a wild-haired orchestra conductor and unleashed a fantastical film that would forever change the way we experience movies. The morning after the gala event at the Broadway Theater in New York City, The New York Times critic Bosley Crowther said, "The music comes not simply from the screen, but from everywhere; it is as if a hearer were in the midst of the music." Even with all the wondrous characters, vivid animation, and whimsical storytelling of this new film, it was the sound that stole the show.
"There is no reason that function should not be beautiful. In fact beauty usually makes it more effective."
Function and beauty can coexist, especially in headphone design.
"I hear the train a comin', it's rolling round the bend
And I ain't seen the sunshine since I don't know when."
"Folsom Prison Blues"
A train horn can be musical, loud and annoying, or even whimsical. But above all it's a communications device.
"If our condition were truly happy, we would not seek diversion from it in order to make ourselves happy."
French mathematician, physicist, inventor, philosopher, writer and Catholic theologian
Are you working in a job that you love? Are you doing a skill that comes naturally to you? Can you imagine doing anything else? If you answered Yes, Yes, and...Yes, then you must be insanely happy. It could be healthy to daydream of doing something else, or even partake in different kinds of productive activities that are wildly different from your career. Studies of scientists have shown that the more varied their hobbies, activities, and other professional pursuits are, the more important and numerous their breakthroughs may be. Performing the same task over and over again becomes drudgery, no matter if you're a widget stamper in a factory or a recombinant DNA engineer in a lab. Our minds need diversion in order to focus when it's important.
"Music's always been at the heart of Apple. It's deep in our DNA. We've sold Macs to musicians since the beginning of Macs."
Twenty years ago this month, Apple officially launched OS X. Apple finally had a legitimate PC killer that would kick the Mac vs. Windows debate into overdrive. In 2001, many studios and video editing companies were already using Macs as the foundation for their digital production systems when OS X dropped, but it literally changed the game.
"Simplicity makes me happy."
Comedian Jim Gaffigan has a classic gut-busting routine about Hot Pockets. After expounding on the unsophistication of eating them, he envisions the meeting with the jingle writer:
Do love that jangle.
Do you think they worked hard on that song?
"What do you got so far, Bill?"
"Uh... uh... (sings) hot pocket?"
"Thats good, thats very good.
The jingle is almost as good as your "By Mennen"
Our daily life has us ingesting "jangles" and other ear worms that have become part of our subconscious. Maybe you've heard these simple sounds over and over again:
"Liberty, Liberty, Li-berty, Liberty"
"Nationwide is on your side"
"Double-A, TOOT-TOOT, M C O"
These sounds are almost as familiar as a logo like the Facebook F, the Micheline Tire man, or the Disney mouse ears. These are all trademarked logos and visual advertising devices. Sounds can also be trademarked as well.
"Well-timed silence hath more eloquence than speech."

"I got a chain letter by fax. It's very simple. You just fax a dollar bill to everybody on the list."
William G.H. Finch had a crazy idea. He liked efficiency, and he liked news. He imagined a future that would merge those together for the average American. Americans like Joe and Jane. When they woke up in the morning, this crazy idea goes, a box in their parlor had just printed out the latest news onto paper with stories and pictures, ready to be poured over while eating their breakfast. Wait – that kinda sounds like the here and now. What's crazy is that this brainchild was born in 1933.

"These fellows blow their horns just to see the people jump, I believe."
Chicago Mayor Carter Harrison, 1902
At the turn of last century, the automobile was poised to overtake the horse as the preferred mode of personal transportation. But there were detractors to the coming sea change. Much as we see driverless cars as a potential danger today, "horseless carriage" opponents saw the drivers themselves as dangerous. Many laws were passed to protect pedestrians and horse-drawn carriages that seem silly now, but these edicts were taken very seriously back then. For instance, a person was required to walk in front of a self-powered carriage waving a red flag; a motorist had to fire off a signal firework every mile; or a driver had to ring a bell or gong when approaching people or other vehicles.
In 1900, the race was on to find the best engine plant for these new-fangled contraptions. Most were noisy and smelly, particularly the steam-powered auto. The ubiquitous gasoline combustable engine wasn't quite developed or refined yet. From 1895 through 1905 the electric-powered vehicle (EV) was the best-selling automobile, partly because it was quiet, easy to operate with its shiftless transmission, and it didn't belch out smoke. But the noisy, smelly, and ultimately cheaper gasoline and diesel engines would win the race. EVs were expensive, technologically difficult, and recharging and range was limited because electric power grids were sparse and in their infancy.
That's a shame, because our world would be a much quieter place had EVs won out as the dominant transportation method. Imagine walking down Main Street USA and not hearing revving engines or loud buses and trucks. Imagine a NASCAR race where the pit crew wouldn't have to wear hearing protection. But would we be safer? Our ears would be, but maybe not our bodies.
In a recent study submitted to the British Parliament by the charity Guide Dogs, it was found that EVs and hybrids were 40% more likely to be involved in an accident that harmed a pedestrian. Blind and limited-sight people can be in real danger around EVs, not to mention all the distracted pedestrians staring down at their phones. I understand this problem because I once skirted serious injury from an electric vehicle. Downtown San Francisco has all-electric restored antique trolley coaches that ride on rubber tires and are very quiet. As I casually stepped off the curb, I just used my ears to "look" both ways. I stopped myself in the nick of time and within inches of a passing trolley coach.
The alarms, bells, gongs, and fireworks have been sounded regarding quiet cars. Starting this year in the European Union (and next year in the U.S.), EV and hybrid vehicles must make artificial noise under certain conditions. When traveling under 12 mph (18.6 mph in the U.S.) or backing up, these vehicles must produce a sound similar to a combustion engine, but no louder. The sound must also indicate speeding up or slowing down, comparable to what a combustion engine would do.
How are the manufacturers responding? Jaguar's first all-electric car, the I-Pace, has a very "Tron" like sound when it accelerates. Nissan's Canto "sings" as it drives. Mercedes-AMG is working with the rock band Linkin Park to find a sound for their luxury cars. And not to be outdone, Porsche offers a $500 option in their EV sports car Taycan called "Electric Sport Sound," which "enhances the vehicle’s own sound and makes it sound even more emotional — both outside and inside the vehicle."
The laws mandating that EVs sound like smog-belching, gas-guzzling cars has me wondering what EVs would be compelled to sound like if they had won the auto race a century ago. Would we be hearing a clopping and snorting Clydesdale? A stagecoach driver whistling and whooping? Time will tell if any of these new solutions work, otherwise we might have to go back to waving a red flag. In the meantime, I'll need to decide which sound my future driverless all-electric car will have. Right now it's a toss up between the Jetson's flying car sound and a horse-drawn carriage.
"Again and again, the cicada's untiring cry pierced the sultry summer air like a needle at work on thick cotton cloth."
Recording location audio outside can be challenging at best. The video team wants an exterior shot because architecture or a landscape in the background can add to the image. But alas, there are often unwanted sounds like cars, HVAC blowers, and other manmade annoyances that we must work around. There's one sound though that is nearly impossible to eliminate, fix, mask, hide, or yell-at-to-be-quiet. It is guaranteed to ruin almost any exterior recording in the summer: the mating song of the cicada.
"It's an interesting place to be. I recommend it."
Astronaut Neil Armstrong commenting about the moon
Every time I hear the timeless phrase Neil Armstrong uttered while stepping on the moon, I can't help but remember the first time I heard it. It was 50 years ago at about 11:00 PM on July 20, 1969. I was eight-years-old and had fallen asleep waiting for them to get out of their strange looking space craft. Our family was vacationing in a cabin on a lake in southern Ohio, and Dad had hauled our portable black-and-white TV from home. We had a lot of trouble getting any TV stations out in the country on that little box. I seem to remember him fiddling with the rabbit ear antennas and positioning all of us at different places in the room like chess pieces so the picture wouldn't flutter.

"It was easier just to say it out on a tape than trying to write it because it will take a lot of writing paper in order to get it straight."
Private First Class Frank A. Kowalczyk
Long Binh Post, Vietnam, 1969
Back when it was expensive, or impossible, to call someone long distance, friends and family members would send messages on records and tapes to each other through the mail. Not only was it more affordable, it was a more personal way to stay in touch with each other and have some fun doing it. When I digitize some of these audio letters for customers, and feel like I'm transported back in time that a way that a letter can't take me.
"Nostalgia is not what it used to be."
Record stores all over America will be opening their doors on April 13th for National Record Store Day. But cassettes are sneaking in through the back. These portable petite plastic packs from the past now have their own Cassette Store Day each year in October, and they're winning over some fans that also shop for vinyl. In fact, annual sales of music cassettes were up 23% in 2018, and 70% since 2016. Artists and studios are rethinking this ancient format and not only re-releasing albums popular during cassette's halcyon days, but new music as well. What's with the retro rewind?
"TV gives everyone an image, but radio gives birth to a million images in a million brains."
The recent presidential elections in Nigeria and Senegal stirred fond memories of my childhood. Specifically the "sounds" of Africa I remember growing up with. I haven't had the good fortune to go to Africa, but I've listened to it from afar. In the 1960s and 70s, radio was perhaps at its peak. AM radio stations played the hits, FM radio played the albums, and CB radios were in kitchens and cars. A lot of homes also had a shortwave radio. Today it's the internet that ties us all together. Back then, CBs connected us with our friends, AM and FM connected us with the country, and shortwave connected us with the world.
My favorite saying is, 'If it's too loud, turn it up.'
You often hear the phrase "The shot heard 'round the world," referring to the first shot fired of the American Revolution in Lexington, Massachusetts. Or for us baseball fans, Bobby Thompson's dramatic game-winning home run when the New York Giants beat the Brooklyn Dodgers for a trip to the 1951 World Series. Both of these pale in comparison to the 1883 explosion of the Krakatoa volcano. Dubbed as the loudest sound in history, it was also the farthest traveled.

Philadelphia Police radio transcripts after the Eagles won the 2018 Super Bowl
Do you remember the old movies from the 1930s when a radio in a police car would blare out "Calling all cars! Calling all cars!" The diligent policemen would zoom away in their car with the siren screaming. The dispatcher had no idea if the radio cars heard the frantic call because two-way radios were uncommon and expensive. So from the late 1920s until after World War II, most police departments relied on their cruisers having radio receivers only. Today, police use digital radio systems that carry data, video, and other information.
"I bought a Dutch barge and turned it into a recording studio. My plan was to go to Paris and record rolling down the Seine."
Pete Townshend, The Who
I'm conflicted on the topic of recording music at home. The business part of me frets about studios losing out on billable hours. The musician part of me relishes creating art in a non-pressure environment. But the history of artists recording radio-ready songs in their humble abodes goes back further than you might imagine. Let's explore how affordable home music recording for the masses came to be, but also look back at the origins of this revolution in recording.
"Hostilities will cease along the whole front from 11 November at 11 o'clock."
Marshal Foch, the French commander of the Allied forces via radio atop the Eiffel Tower.
This week marks 100 years since the end of the war to end all wars, known today as World War One. In 1918, on the 11th hour, on the 11th day of the 11th month, 1,500 days of fighting came to an end. The armistice was agreed upon just six hours earlier in a railway car halfway between Paris and the Western Front. What's remarkable is the speed at which most troops were informed of the impending armistice. This war, like in so many other ways, forever changed the world of communication.Read More...

From the gold records aboard the twin Voyager spacecraft
Vinyl is the format that won't die. It'll probably still be around after humans are extinct and our sun has gone supernova. Perhaps in eons, Voyager spacecraft with the golden records aboard will meet distant stars and future vinyl lovers. But in this eon, people will not stop pushing vinyl to its limits. Mad scientists and crazy artists like putting something other than music on it - or in it. More on that later.Read More...
"Treat the recording studio as a laboratory for conceptual thinking — rather than as a mere tool."
When I was young in the...cough...60s and 70s, the only real glimpses I got inside a recording studio was through television and movies. There was a smattering of documentaries and behind-the-scenes footage of studios and radio stations. I was always straining to see the control board and tape machines, or marveling at the cavernous studio on the other side of the glass. It was absolutely riveting to peek inside them and see how a record was made. The 8-foot long mixing console was often shot through a fisheye lens. Long-haired musicians were sunk down into a couch smoking cigarettes (?) and listening to their masterpiece. And there were close-up shots of that big fat 2-inch tape rolling past the heads of the recorder.
"The people will waken and listen to hear
The hurrying hoof-beats of that steed,
And the midnight message of Paul Revere."
Henry Wadsworth Longfellow
What did Paul Revere's famous midnight ride from Boston to Lexington sound like in April 1775? If you were there, you might recognize the approaching horse as a Narragansett Pacer mare. This once popular breed of horse, now extinct, was known for its ambling gait: a smooth riding four-beat gait that is faster than a walk, but slower than a canter or gallop. You might also notice the calm surroundings interrupted occasionally by crow calls, trees rustling in the wind, or the occasional farm dog barking at the stranger barreling down the rough dirt road. Just someone in a hurry.
"I have been at work for some time building an apparatus to see if it is possible for personalities which have left this earth to communicate with us."
Thomas Edison, 1920
What if you nonchalantly recorded something around your house, let's say a music practice session. Then when you played it back, you clearly hear someone whispering. You didn't hear it when you recorded it, so what was it? Many unfamiliar sounds throughout history can be attributed to nature, machinery, and even hoaxes. As our post-industrial society grows, so does the list of unexplained sounds, like trumpet sounds from the sky, humming cities, and ocean whistles. The proliferation of audio and video technology has generated its own tally of the strange. Specifically, weird voices that have been inadvertently and unknowingly captured. These recordings and transmissions sound eerie but have a very unsexy-sounding name: "Electronic Voice Phenomenon," or EVP.
"Any sufficiently advanced technology is indistinguishable from magic."
Arthur C. Clarke
To the average person, audio can be a
mysterious "myth-terious" thing. Many people don't want to admit that they are intimidated by the technical side of it, and that makes sense. The closest most people get to manipulating audio is adjusting the volume on their stereo. I bust 10 common myths about recording audio.
"The opera ain’t over until the fat lady sings."
Ralph Carpenter, Texas Tech Sports Information Director
Richard Wagner, the 19th century German composer, would have loved Star Wars. He may not have understood what a light saber or X-Wing fighter was, but he would get it - even with his eyes shut. That's because the Star Wars films are rich with composer John Williams' scores that employ a musical tool that Wagner himself was a master of: the leitmotif.
"If we knew what it was we were doing, it would not be called research, would it? "
Bell Labs was born more than a hundred years ago out of the need to improve the nascent telephone. It grew into a pure research facility that made an astounding number of scientific discoveries, improved or invented new technologies, and even influenced art and music.
"Analog is more beautiful than digital, really, but we go for comfort."
There's been a growing trend over the last several years to bring back the sound of classic analog gear, such as compressors and amps with vacuum tubes, ribbon microphones, and even reel-to-reel tape. Let's look at how old school charm is finding new love.

"Every crowd has a silver lining.”
126.4 I think that's what will be inside a little oval sticker that I'm going to put on my bumper. I see "26.2" bumper stickers that marathon runners proudly display. Colorado mountain climbers have "14er" stickers. A lot of dads are number "1." Then what's so special about 126.4? It used to be a number for Kings, but now it's a number for Cats.
Before I start to sound like a broken record, let me back up and tell this story from the beginning. Team Cornett wanted to raise the profile of UK Health Care and their close association with UK Athletics, so they came up with a plan to get the attention of a sports crowd. There's no better place for a hyped up crowd than Rupp Arena in downtown Lexington. With nearly 24,000 people, its been known to get really loud in there. It would be the perfect place to try and break the world record for the loudest crowd roar at an indoor sports event. And what basketball game would have the biggest and loudest crowd? A made-for-ESPN-TV marquee matchup: Kentucky versus Kansas.
"The key to this plan is the giant laser. It was invented by the noted Cambridge physicist Dr. Parsons. Therefore, we shall call it the Alan Parsons Project."
Here's something that will blow your mind and make you paranoid at the same time. Someone can listen to your conversations in your house or office from hundreds of feet away using light. The "light" is a "laser," and it's bounced off a window pane to detect sound vibrations. It's hard not to imagine Dr. Evil, played by Mike Meyers, air quoting "laser" when we mention that word. The theory was first proposed in the 1940s, but had to wait until lasers were actually invented in the 1960s to gain traction. By the 80s, the Cold War had us and the Soviets spying on each other using "lasers."Read More...
“Square in your ship's path are Sirens, crying beauty to bewitch men coasting by;
woe to the innocent who hears that sound!”
by Homer in The Odyssey
I live on a busy street. My house sits roughly between three hospitals - all with helipads and emergency rooms. That's good for me if I have a really bad day, but my poor cat thinks wolves are after her whenever someone else is having a really bad day. I'm talking about the incessant sirens going up and down my street. And they seem to be getting louder – they penetrate my windows and brick walls with even more ferocity than ever before. It turns out that I'm not imagining this, because some emergency vehicles are now employing something called "low frequency system," or LFS. I call it "Loud F*@#$%^& Siren."
In addition to the regular high yelp of a siren, you may have noticed a lower yelping sound that seems to penetrate your car and go straight through your chest. That emergency vehicle has a secondary siren system that emits powerful omnidirectional bass tones from about 200-400 Hz. In this range, sound is "felt" more than heard - up to 200 feet away. These frequencies can penetrate auto glass and metal, wood and brick buildings, and human flesh and bones.
"I used to judge the quality of music by whether I could make a 90-minute cassette and not repeat any artists."

A lot of people aren't, and the FCC is out to change that. The FCC? You bet – this isn't your father's FCC. We're so used to hearing "FCC" and "restrictions" in the same breath, that broadcasters were pleasantly surprised last October when the FCC announced an "AM Revitalization" initiative.
"I throw more power into my voice, and now the flame is extinguished"

"As so much music is listened to via MP3 download, many will never experience the joy of analog playback, and for them, I feel sorry. They are missing out."
There's a growing trend in the music business - recording to reel-to-reel tape. Wait, I thought we got rid of that when we went digital. The truth is, it never went away. Much like the recent boom in sales of records and film, reel-to-reels are gaining new fans and bringing back old ones.
"I hope I inspire people who hear. Hearing people have the ability to remove barriers that prevent deaf people from achieving their dreams."
Did you know that more than 37 million Americans aged 18 or older have some kind of hearing loss? And 30 million Americans aged 12 or older have hearing loss in both ears? With a media-rich society, that makes listening to narration, dialog, and speech in general difficult for them. Before 1972, anyone hard of hearing had to watch television with the volume turned up.
"If it weren't for Philo T. Farnsworth, inventor of television, we'd still be eating frozen radio dinners."

Max Baer, Jr. as "Jethro Bodine"
Double-Naught SpiesThis month, the new James Bond spy movie Spectre will be released. It's the 24th film in the long-running franchise based on Ian Fleming's novels. "Hot Dog!" as Jethro Bodine would say. James Bond and all his gadgets were hatched from Fleming's experiences while serving in the British Navy Intelligence Division during World War Two.
Gathering intelligence during any war requires innovative and clandestine communication techniques, especially deep within the enemy lines. In the Revolutionary War, invisible ink and garments on a clothesline were tools to send secret messages. The Civil War saw women disguising themselves as nurses, slaves, and even soldiers to gather and smuggle information. During World War One, the human body itself became a vehicle for secret messages via invisible tattoos. Read More...
"Podcasting - I swear to you - on its worst day, the podcasts are better than our best films. Because they're more imaginative, and there's no artifice, and it's far more real."
Podcasting RevisitedModern podcasting has now been around a little more than 10 years now. The roots go back much further, into the 1980's in fact. The idea of subscribing to an internet-delivered audio service dates to the early 1990's. But it wasn't until portable devices, such as the iPod, came onto the scene that it really took off. History shows that portability drives popularity – the battery-operated radio, the portable record player, the audio cassette, and the funky 8-track. I remember the iPod being described as a digital "Walkman," even though poor Sony already had moved beyond the cassette into portable digital players. Read More...
"Science is magic that works"
That Magic Sound
Researcher Dr. Diana Deutsch at UC San Diego has been studying the psychology of sound since the mid-1960's. Her findings illustrate how people can hear musical tones wildly different from each other. These "illusions" can cause great disagreements between listeners, even highly trained musicians. And interestingly, one group of stereo illusions has right-handers and left-handers perceiving them differently. Read More...

Gordon Hempton, an Emmy-Award-winning recordist, claims there are less than a dozen places left in the continental U.S. that are "quiet." Hempton defines "quiet" as a natural environment that has no human-intrusion sounds for at least twenty minutes. Read More...
"In radio, they say, nothing happens until the announcer says it happens."
Legendary Detroit Tigers Announcer
There was a time when Americans who wanted to sound important and upper class spoke with a half-American, half-British accent. They call it mid-Atlantic, presumably because the accent lands somewhere in the middle of the ocean between our countries. It was dominant in movies, on radio, in theaters, and on early television. Today, it sounds pompous. Some early practitioners were Franklin Roosevelt, James Cagney, Orson Wells, and Katherine Hepburn. Some more contemporary holdouts were William F. Buckley, George Plimpton, and Jacqueline Kennedy Onassis.
"Words mean more than what is set down on paper. It takes the human voice to infuse them with deeper meaning."
There was a recent study* that tried to understand how audio quality affected the perceived quality of the human voice. The researchers understood from the beginning that the results could be highly subjective, but they approached it using measurable methods. While tallying up the results, they were surprised by one finding they weren't attempting to measure. But it's something we in the advertising and production business already knew. Read More...
“Even if you're on the right track, you'll get run over if you just sit there.”
3D Audio on the Right Track
It's said that when an early motion picture was first shown to the public, women fainted and men ducked from an approaching train. The director made a bold new decision that would alter the course of filmmaking for the next century. Instead of just placing the camera in front of all the action like an audience watching a stage, the director moved the camera to a new position - within the action - to create perspective. That’s been happening in filmmaking ever since. But the same has been happening in sound as well. And now with emerging technologies, virtual 3D sound is now here. Read More...

The Color of Sound
How would you describe a sound to someone without using descriptors that are unique to sound, like: loud, bassy, shrill, whining, atonal, or noisy?
Not a problem, because we most often describe a sonic experience with words related to our other senses: sharp, warm, angular, raspy, piercing, even, warbling, soft, smooth, or flat.
What about blue? I think of that as more of a style of music or mood instead of a type of sound. Why don't we use more colors to describe what we hear? Probably because a "yellow" sound could be cowardly. A "green" sound may be eco-friendly. A "purple" sound is probably regal. A "brown" sound - well, we'll leave that one alone.
What if we could see sound? Aside from graphical representations of sound like waveforms and meters, we can't just look at an orchestra and see sounds flying out of the trombones. I wish we could watch the beautiful tones flow from Itzhak Perlman's Stradivarius.
But we can - sort of. As reported by NPR, we can see certain sounds using a technique invented in the mid-19th century. Click on the link above to read about and watch a short video describing this process to get a clearer picture. To simplify, scientists watch the disturbance of heat waves by sound. Ever look down a highway on a hot summer day and see the heat creating wavy images? Scientists have used this phenomenon to "see" sneezes and aircraft wing turbulence. But Michael Hargather at New Mexico Tech uses it to study explosives.
So what's next? I would love be able to put on some goggles and see sounds and where they're coming from. Loud sounds would be bright. Bass would be blue, treble would be white, and green, red, and yellow would fill in the gaps. Imagine seeing green waves and ripples emanating from the violas, bubbles of blue from the tuba, and distinct columns of yellow and white from the violins. It would be like Peter Max was the conductor. With technology advancing at such a rapid rate, this may not be so far-fetched in our lifetimes. Color me crazy.
Did You Know?
- "White noise" in sound engineering describes randomly generating all the sounds in the frequency spectrum. SInce the sounds aren't generated at the same time, they are measured over a period of time. Each sound is at a consistent level.
- White noise sounds similar to a radio that is tuned to no station.
- White noise is often used in large offices to mask sounds from workers, computers, and other office machinery. People also use white noise generators to aid in sleeping.
- "Pink noise" is similar to white noise, but decreases in intensity each ascending octave.
- Pink noise is primarily used to measure the output of an audio device.
- Sound engineers play pink noise over monitor systems to check frequency response and level of speakers. If measurements show that a speaker produces some frequencies differently than the pink noise (more bass for example), then it is considered to have a "colored" response. Pro audio speaker manufacturers strive for a "flat" response from their products. This way an engineer isn't fooled into compensating for the difference while mixing.
- Live sound engineers use pink noise to reduce feedback and get maximum performance from speakers.
- Other types of noise used in analysis are violet, brown(ian), gray, blue. Other informal names for sound used in measurement are red, green, black, noisy black, and noisy white.
Tech NotesReducing feedback in a live sound situation is very tricky, especially if good sound performance is desired. The "squeal" you hear when a microphone is turned on is from a buildup of a certain frequency. It's usually the point at which the microphone and speaker are the most efficient. If one points a microphone at the same speaker that is amplifying it, then serious feedback occurs. Most speakers are placed in front of or beside performers so there is no direct bleed back into the microphone. If speakers are placed behind the performers (think The Who), then eliminating feedback is a bigger chore.
How do you eliminate feedback? Let's use the simplest set-up as an example: one microphone and one speaker. A graphic equalizer (GEQ), a device that increases or reduces frequency by octaves, is inserted after the microphone channel and just before the amplifier. The engineer slowly raises the amplifier level until the first inkling of feedback. Using the GEQ, the engineer locates the offending octave, ex: 630 Hz, by actually increasing that frequency creating more feedback. That octave is then reduced until feedback goes away.
Next, then amplifier is turned up a little more until the next inkling of feedback occurs, usually at another frequency, which is then reduced. These steps are repeated over and over until the amplifier is at a suitable level without feedback. Of course computer technology has simplified this process greatly with devices that rapidly reduce feedback "on-the-fly." And with software, engineers for permanent PA systems in large venues can even predict where feedback will occur before installation. They can then program in filtering or make changes to the architecture, equipment, or speaker placement.
Turn it Down!The volume is getting turned down on television commercials. What does that mean for you, the producer or advertiser? Well, you can still scream all you want, but you just won't be louder than the latest installment of a Fast and Furious movie. The CALM Act (The Commercial Advertisement Loudness Mitigation Act, 2011) that President Obama signed into law last December mandates that TV stations and networks reduce the volume of commercials to match the program level. How will they comply? The simplest method is to install equipment that automatically balances the commercials with the program. However this solves one problem and creates another - the perception of loudness remains, even though the volume is lower. This is all because of "dynamic range," or lack thereof.
Let's say you have a one-gallon bucket sitting on your lap as you race your Fast and Furious hot rod through the streets of Tokyo. However, it's not water that's in that bucket - it's hydrochloric acid. And you must have the bucket as full as you can without spilling any acid. If you fill it to the rim, you'll surely spill it, so you opt for half full because of your wild race. The acid wildly splashes around inside the bucket's free space but doesn't land in your lap. This "free space" is called headroom in the audio world. It's how much audio space you have above the average dialog for things like sound effects and music to peak. This creates more impact between the elements, and is closer to the way we hear real life sounds. Movies and television dramas use this space very effectively. But when a commercial comes crashing in, it's occupying ALL of this free space, with very little headroom. It's like taking a pit stop and having a bucket completely full of acid put in your lap.
It's pretty unfair to fully burden the broadcasters with policing the sound levels. It starts with producers, recording studios, and advertisers to not fill that bucket up in the first place. The biggest challenge we engineers have when mixing commercials is how to squeeze voice, music and effects into a very small space where everything is loud. If we expand the dynamic range from the start by lowering the narration, then our commercials should better blend with the program. Let's calm things down and take a nice Sunday afternoon drive in the country instead.

How do we know where to put sound levels when mixing? The average dialog level is placed at a certain volume depending on where the program will be heard, such as movie theater, DVD, or television. This "average" level is measured using a slow-moving audio meter. OK, you're going to have to think in reverse to understand the next part. The meter we use has a scale from 0 (loudest) to about -60 (silence). Average cinema dialog usually rides around -20. The average television program averages -14 (this is louder than -20), with commercials and sports around -12 (slightly louder than -14). The reason cinema's lower is to have more headroom for sound effects. Also, theaters are able to handle the higher levels because of their robust sound systems.
Sometimes commercials are mixed with an average dialog level between -6 and -10, significantly louder than television programs. Both commercials and programs are still within limits, but the commercials are pounding the loudest portions of the scale. This limited dynamic range is why it's so difficult to fit narration, sound effects, and music into this tight space.
And Down the Stretch They Come!A jam-packed field. Each running neck-and-neck trying to lead the pack. The whole mass moving toward the finish line with breathtaking speed. Finally it ends, but it's too close to call!!!
No, it's not the Kentucky Derby. It's an overcrowded commercial with too much information that's been crammed into 30 seconds. Sound familiar? We all want to get our message across, but we often say too much. I'm guilty of it (as many of my friends would attest).
What's my point? Your audio engineer at Dynamix Productions is not one-dimensional. We can also be a part of your creative team; your copy writing staff; your proof reader; your client liaison. In other words, we're not just button pushers. During your recording session, we can offer scripting advice so that your message is not cluttered. If one sentence sounds better rewritten as two sentences, we can suggest how. If your brand is not standing out enough, we can point out ways for more emphasis. We are experts at understanding that scripting for narration is much different than for visual mediums like print and web. We want your message to be clear and concise, without getting bumped, ran into the rail, blocked out, or flat out beaten. Oh, and horse racing lingo? We do a little bit of that, too.

So what do you do when you do need to cram too much information in a short amount of time? "Time Squeeze" to the rescue! In the old analog days, engineers used to speed up a tape or record to make it run faster. However, the audio was pitched up and started sounding like Mickey Mouse. Digital time-squeezing solves the pitch problem by mathematically throwing out data. Smoother sounds can be attained by matching the right algorithm with the content. Although voice-over is less complex than time compressing music, it can perhaps be the trickiest. Our ears (and brains) are designed to be experts at listening to the human voice. Any deviation from "normal" can be detected almost instantly. Therefore, we like to quote the "ten-percent" rule when digitally reducing time. Once a voice is time-squeezed more than around ten-percent, it starts to sound fake. Therefore, a recording that is 33 seconds long can be time-squeezed by 3.3 seconds to about 29.7 seconds without sounding too processed.
However, when you time squeeze this much, you will lose the spacing and leave sentences butted-up against each other. We like to build in spacing with breaths deleted and tightened before the final "squeeze." This at least retains a little "air" and personality.
Just like all rules, it doesn't always hold true. Hard and short sounds like "k," "t, and "p" are shortened even more and sometimes disappear all together. If we are planning a dramatic time-squeeze, as in a legal disclaimer for instance, the narrator will read slowly with exaggerated emphasis on consonants so they won't get too truncated.
What about adding time? "Time-stretching" does the reverse and adds in information. Here we use the "six--percent" rule. Anything longer makes the narrator sound drunk and makes for some good laughs. But it can be a little eerie when you push it too far and it doesn't make much of a difference. That guy must have drank his lunch!
Recreating the Sounds of the Civil WarBeing in the "Horse Capital of the World," we surely have enough experience to know that a horse sounds much like it did 150 years ago. However, back then a horse's role was very different than today. In a new documentary, "Unsung Hero: The Horse in the Civil War," produced by Witnessing History, LLC for HRTV (Horse Racing TV Network), the role of the horse in the American Civil War is explored in-depth with rarely-seen photographs, documents and artwork. To a sound designer's delight, there are simulated battle scenes, troop movements, and other war action. Some are new videos of re-enactors, and others are artwork and photos. The opoortunity to bring these to life with sounds and music is why we love what we do. Dynamix Productions has previously produced soundtracks for two Civil War documentaries ("Long Road Back to Kentucky" and "Retreat from Gettysburg"), so our cache of sound effects has been growing. We even did field recordings during two re-enactments as well as studio recordings of Civil War-era weapons.
Every documentary requires its own approach as to how realistic or dreamy the sound effects are. In "Long Road Back," many scenes were very specific with close-ups of cannons, guns, and fighting. These took on an almost movie-like feel. In "Retreat," we backed off some and chose more ambient sections, with a sprinkle of realistic moments. It had many scenes of soldiers marching, so we created large troop movements from scratch by layering walking and marching with different shoes and surfaces. In "Unsung Hero," there are minimal re-enactments, so general background sounds supported by emotional music lift the visuals. More horse sound effects were used in this documentary than the other two. Each story is unique, that's why there were three different approaches to one era of time.
Dynamix Tech Notes
How do you record a cannon? Very carefully! Actually, it pays to buddy up with the gunners and learn the sequence of operation. During a Civil War re-enactment several years ago I needed to record cannons for a documentary. By talking with the crew I learned what orders were given during certain phases of loading, firing, and cleaning. I was located a hundred feet or so from the cannons, so I had to carefully watch hand signals. I also learned that the sound of live round cannons are very different that blanks. Thankfully they weren't going to shoot live rounds that day with a crowd, so I had to settle with blanks - still very loud.
The largest technical challenge was the extreme sound pressure, or loudness. You actually feel the shock wave hit you when a cannon is fired. A tiny, delicate, and sensitive microphone wouldn't handle this very well. I had to use microphones that could handle the loud sounds, the same kind usually used for percussion. To increase my success rate I recorded each shot at different levels, reducing it on each shot. The last bit of the technical puzzle was a recorder capable of recording high dynamic ranges. These cannons were definitely louder than the threshold of pain (130 dB-SPL) and a jet engine at 100 feet (150 dB-SPL). Because of tremendous advances in technology, my recorder was able to record at least 48 dB more sound level than what was available just 15 years ago. That's a factor of almost 100,000. It's pretty much the difference between a cannonball and a mountain.
